thework without riskofinjury or damagetothe machine.

See figure 3.1.

• To avoid interruptions and inconvenience during cutting,

planyourwork so that youfittheblade on the mostsuita-

ble side of the saw right from the start.

• Check that you have the correct diamond blade for the

FS800 E/EM and the material you intend to cut. See

section 9 Technical specifications.

• Check the direction of rotation before fitting the blade.

Raise the blade guard on the side where you want to fit

the blade. Secure the blade guard with the retaining

strap. Connect the power cable and press the switch to

start the machine. Check that the blade flange rotates in

the direction shown by the arrow on the blade guard. If

the flange rotates in the wrong direction, turn off the

switch to stop the machine, then unplug the power cable

from the machine. Turn the phase inverter in the socket.

Stop the machine as described above and recheck.

• Check that the blade is not worn; each of the diamond

segments must project at least 1 mm. They must also be

wider than the body of the blade. See figure 6.3.

• Check that none of the diamond segments is damaged.

• Fit the blade so that the arrow on the body of the blade

matches the direction of rotation of the shaft. Tighten

the blade flange using the pin spanner supplied, while

using the other spanner to prevent the blade shaft from

turning. See the instructions in section 6, Fitting and

replacing diamond blades. See figure 6.1.

• Lower the blade guard over the blade.

• Check that the blade is straight by turning the blade by

hand and measuring the gap between the blade and the

blade guard. If the blade is misaligned or uneven it must

be replaced.

• Check that both the blade guard and the blade flange

guard are correctly fitted, then lower them.

• Make sure the emergency stop is not deactivated. The

emergencystop must not bedeactivatedduring operation.

• Before starting the floor saw, raise the blade so that it

rotates without touching the surface.

• Connect the power cable to the power socket.

• Connect the water-cooling hose to the coupling that runs

from the blade guard.

• Check that the water supply is adequate and that the

nozzle is not blocked.

• Make sure that the power cable and water-cooling hose

from the floor saw will not get trapped underneath or in

front of the machine when you start up or during cutting.

• Use the safety equipment specified in the safety precau-

tions on page 5.

WARNING

Make sure that you are not

working on a floor that could

give way underneath you.

WARNING

Do not cut on a steep

incline as the blade

could jam.

WARNING

Do not use the saw where

there is a risk of collapse.

• Check your safety equipment and any protective clothing

you are wearing.

• Apply the parking brake.

• If the machine is fitted with a base plate (optional acces-

sory). Lower the base plate by raising the safety catch.

• Turn on the cooling water to provide adequate cooling

and prevent dust formation.

• Release the parking brake, while holding the guide hand-

le on the machine with your other hand.

• Turn the height adjustment wheel clockwise to lower the

blade to a depth that is suitable for the material you are

cutting, but no less than 20 mm.

• Cut a guide slot at this depth, moving steadily along your

marked line. When you have completed the guide slot,

turn the wheel to raise the blade, turn off the cooling

water and stop the saw by pressing the red switch. Drag

the machine back to the starting point.

• Realign the floor saw with the guide slot with the aid of

the alignment guide, then start the machine as described

above.

• Lowerthesaw blade to a suitable depth.Therightcutting

depth depends on the composition of the floor and the

cutting speed. Generally, if the floor saw tries to climb up

out of the slot then the cutting depth is too deep and/or

the cutting speed is too high. The floor saw must not be

advanced so fast that the blade tries to climb out of the

slot. Adjust the cutting depth.

• Advancethemachine smoothly and methodically, making

sure that the alignment guide always follows the guide

slot.

5. Maintenance

NOTE!Alwaysdisconnect the power cables before carryingout

any maintenance, repairs or servicing.

• Cleanthe machine after completing a series of cuts. Note!

Avoid spraying water at the electric motor and wiring.

• Lubricate the blade shaft bearing at the end of each day's

use. During intensive cutting the blade shaft must be

lubricated several times a day. Always use high quality

water-resistant grease.

• Lubricate all other grease points at least once a week, or

more often if necessary. See figures 5.1.1-4 and 5.4.1-2.

Grease the wheel bearings as necessary. See figure 5.1.5.

• The safety devices are provided for your safety, so it is

extremely important that you check all safety equipment

regularly. If you discover a fault, contact your supplier.

NOTE! Do not start the saw if you know that any of the

machine's safety devices is faulty.

• Keep the machine's drive belts free of oil, dirt and dust.

Check the belt tension regularly as described below. If the

beltsrequiretensioning,usetheadjusterscrew in front of

the drive motor. Turn this clockwise to tighten the belts.

See figures 5.2.2 and 5.3.

• Check the condition of the diamond blade regularly to

make sure it is not damaged or worn down. Replace the

bladewhen the segments areworndownor have become

narrower than the body of the blade.

• Check that the water supply is working correctly. If not,

clean the nozzle. See figure 5.2.1.

• Regularly check that electrical wiring and couplings are in

good condition and that all screws are tight.
